Commercial printing systems generally include a digital front end (DFE) that processes incoming print jobs in the form of page description language (PDL) files to create the print-ready images, as well as a print engine that receives the images and prints the images onto paper or other printable media. Clutching can occur when print-ready images are not generated as fast as a print engine prints the images. In certain types of printing systems, such as web-fed printing systems in which a continuous spool of printable paper is fed into the print engine, clutching is undesirable, particularly for variable data or indefinite length transactional jobs, wherein unfused images can be placed on the paper web and recovery of a job may involve complicated steps of cutting out the defective printed area from the paper web. Clutching can be partially mitigated by buffering a fixed number of print-ready images prior to starting the print engine. However, this approach does not avoid clutching for indefinite length jobs, since the buffer can exhaust if the DFE processes the remaining images at a slower rate than the print rate. Alternatively, the entire incoming PDL job file can be processed and buffered prior to providing any images to the print engine, but this would require huge amounts of buffer memory for indefinite length jobs, such as printing hundreds of thousands of credit card statements, phone bills, etc. This approach also suffers from an indefinitely long time between provision of the PDL print job to the DFE and the time when the first image is actually printed. Thus, there remains a need for improved printing systems and methods by which the adverse effects of printing system clutching can be avoided or mitigated.
